objective c - How to use NSPointArray? -

-

so want use method appendbezierpathwithpoints:count: in nsbezierpath. method requires me use nspointarray. documentary doesn't talk , it's array of nspoints , i'm not sure how it. think uses c array mechanism, i'm not sure.

thanks.

yes, need c-style array of points pass appendbezierpathwithpoints:count:. example might this:

nspoint pointarray[3];  pointarray[0] = nsmakepoint(0, 0); pointarray[1] = nsmakepoint(0.5, 0.25); pointarray[2] = nsmakepoint(1, 1);  [lines appendbezierpathwithpoints:pointarray count:3];

where lines instance of nsbezierpath.

in more complicated case you'll use variable number of points say.
